Serial Communications Interface (SCI)
Serial Communications Interface (SCI)
OR — Overrun Error Flag
OR is set if a new character is received before a previously received
character is read from SCDR. Clear the OR flag by reading SCSR and
then reading SCDR.
0 = No overrun
1 = Overrun detected
NF — Noise Error Flag
NF is set if majority sample logic detects anything other than a
unanimous decision. Clear NF by reading SCSR and then reading
SCDR.
0 = Unanimous decision
1 = Noise detected
FE — Framing Error Flag
FE is set when a 0 is detected where a stop bit was expected. Clear
the FE flag by reading SCSR and then reading SCDR.
0 = Stop bit detected
1 = Zero detected
Bit 0 — Unimplemented
Always reads 0
7.3.5 Serial Communications Data Register
NOTE:
SCI receive and transmit data are double buffered. Reads of SCDR
access the receive data buffer and writes access the transmit data
buffer.
